I've read on Wikipedia about Space Weathering. It's described as the type of weathering that occurs to any object exposed to the harsh environment of outer space. Unlike on Earth, a man-made vessel wouldn't be affected by rain or wind. But the constant flux of high energy particles and micrometeorites.
If I've understood the article, it appears that over time Space Weather would darken man-made materials. But the article describes melting and vapor as well.
What would this look like over time? I assume painted surfaces would show the same weathering. Are there any examples of man-made devices where we've actually seen space weathering?
